The behavior of an annular plate, free at its inner edge and simply supported at the outer one is investigated experimentally. The loading is a compressive inplane force which is uniformly applied at the outer boundary. Deformations, strains frequencies and mode shapes are explored over sub, trans and post buckling regions. Experimental results for the buckling loads, obtained by different methods are compared, and comparison is also made with existing theoretical data. An approximate formula for the vibrations of the loaded annular plates is developed and compared with the experimental results.
